R5460N210AD-TR-FE 产品概述

一、产品简介

R5460N210AD-TR-FE 是 NISSHINBO 推出的二节锂电池保护芯片,封装为 SOT-23-6,适用于两节串联锂电池组(如 LiFePO4 或其他需要 3.65V 饱和电压的锂电 chemistry)。芯片工作电压范围 1.5V ~ 10V,工作温度范围宽(-40℃ ~ +85℃),集成过充、过放、过流和短路保护,并支持 0V 电池唤醒充电。器件静态电流仅 1.2 µA,适合对待机耗电敏感的便携与长期待机类产品。

二、关键功能与保护机制

  • 过充保护:当电池单体电压达到充电饱和电压(3.65V)时,芯片执行切断充电路径,防止过充损伤电池。
  • 过放保护:当电池电压下降到放电截止电压(2.5V)时,切断放电路径,避免电池过度放电。
  • 过流保护:对充放电过程中的过流事件进行检测并限流或断开,保护电池与负载。
  • 短路保护:快速响应短路条件,迅速断开输出,降低能量损耗与安全风险。
  • 0V 电池充电支持:对电压为 0V 的电池提供预充电/唤醒功能,适用于深度放电后的电池恢复。
  • 低静态电流:Iq = 1.2 µA,降低整机待机漏耗,延长电池待机寿命。

三、典型应用场景

  • 便携式设备:蓝牙耳机、手持终端、便携式仪器等需要低待机耗电的场合。
  • 储能与电源管理:小型 2S 电池组保护模块、便携电源、UPS 后备电源等。
  • 物联网节点与传感器:长期部署、低功耗要求高的终端设备。
  • 工业控制与照明:在宽温范围(-40℃~+85℃)内仍能稳定工作的应用场景。

四、设计注意事项

  • 电池类型匹配:本芯片标配 3.65V 充电饱和电压与 2.5V 放电截止电压,最适合 LiFePO4 类型电池或具有相同阈值的锂电体系。在用于其他化学体系(如标准 Li‑ion)时,应核对实际电压限值与电池厂商建议值是否匹配。
  • 温度检测:芯片不支持内置电池温度检测,建议在对温度敏感或需要符合更严格安全标准的设计中增加外部温度监测与切断逻辑。
  • 0V 唤醒:虽然支持 0V 充电,但深度放电电池恢复需谨慎,建议在上电与预充阶段监控充电电流与温升。
  • 布局与散热:SOT-23-6 为小封装,过流与短路事件会产生热量。合理安排 PCB 大地铜箔、粗短的电流走线并靠近电池端子布局以降低接触电阻与温升。
  • 保护阈值与周边元件:实际应用中需查看完整数据手册以确定过流限值、延时特性和是否需外部限流电阻/MOSFET 等配合器件。

五、封装与采购信息

  • 品牌:NISSHINBO
  • 型号:R5460N210AD-TR-FE
  • 封装:SOT-23-6
  • 适用电压:工作 1.5V ~ 10V
  • 主要特性:支持 2 节电池、3.65V 充电饱和、2.5V 放电截止、0V 充电支持、Iq=1.2µA、过充/过放/过流/短路保护 采购或设计前请下载并参照厂家最新数据手册,以获得精确的电气参数、引脚定义、典型应用电路与可靠性信息。

总结:R5460N210AD-TR-FE 以其低静态电流、全面的保护功能和宽工作温度特性,适合各类 2 节锂电池组的保护设计。对需支持 0V 唤醒及低待机功耗的便携产品尤为合适,但在关键应用中应配合外部温度监测与合理 PCB 布局以确保安全可靠运行。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
